Hi, The constraint "Ch_DCh(i) .. Pch(i)*Pdch(i) =e= 0;" make the model non-convex and hard to debug (you need a global solver). Since the rest of the model is linear you should implement the logic with a binary variable: binary variable b(i); Ch_DCh1(i) .. Pch(i) =l= b(i)*bigM; Ch_DCh2(i) .. Pdch(i)...

Priyanka, I can see a problem with these constraints. ch_dis_lobinary is superfluous, but that's okay. When you say that "I am not getting the correct results" what do you mean. Do you have both I_ch and I_dist 1, or are the Pch and Pdis not 0 or between bounds? First of all make sure you get an opt...
